Is ‘Moral Compass’ a Rubbish Idea?

For many people, the idea that we have been given a moral compass by a deity that shows us the difference between right and wrong is an attractive one. For that one third of the human population that makes up the Christian – Muslim – Judea versions, morality has been handed down in recent history, the last 2000 years or so.
By default, for the preceding 200,000 years, possibly 300,000 years, humans had no sense of family, loyalty or other positive attribute and we killed and raped and plundered indiscriminately.
If the deity was the creator of the earth and mankind, that means the deity watched with little interest for hundreds of thousands of years and then, just recently, in the last 1% or less, of that time, decided to intervene.
Depending on which of the aforementioned religions one subscribes to, this intervention was either causing itself to arrive on the planet in the normal way, by birth as a son of the deity and arranging for this son to be tortured and killed for our sins or as a prophet in direct contact with the deity but still suffering the same fate. Not a lot of logic going on here.
